The Oakland Raiders may be done with Antonio Brown, but it appears he is not yet done with them.

ESPN’s Jeremy Fowler reported Friday that Brown is working on a “potential grievance” against the Raiders, attempting to recoup some of the $30 million in guaranteed money that was voided when the team released him earlier this month.

According to the report, the NFL Players Association is also looking at ways Brown can get money back.

Citing a source, Fowler said among the money Brown wants back are three fines handed down by the Raiders, his Week 1 salary, his base salaries for this and next season totaling north of $29 million and a $1 million signing bonus.

Multiple reports in recent days also said Brown would file a grievance against the New England Patriots, who signed Brown after he was let go by the Raiders, then cut him after only one game.

Yahoo Sports reported Friday that five league sources agreed that Brown is likely to win a grievance over the $9 million signing bonus the Patriots are refusing to pay him. According to those sources, Brown was not released for any conduct outlined in the collective bargaining agreement that would allow a team to void bonuses.

A week before Brown was cut by New England, his former trainer filed a civil suit accusing him of three incidents of sexual assault or rape over a two-year period from 2017-18. Then the day before Brown was cut, Sports Illustrated reported that a second woman who claimed Brown made unwanted sexual advances toward her told the NFL Brown had sent her “intimidating and threatening” texts.

According to the Yahoo report Friday, by playing Brown in a game after learning of the civil suit, the Patriots will have a difficult time claiming the suit as a reason to void his bonuses.

The Patriots signed Brown earlier this month just hours after the Raiders released him. Brown spent training camp in and out of team facilities, rehabbing a frostbite-like condition on his feet after a cryotherapy mishap, filing grievances with the NFL over his helmet, arguing with team management (reportedly calling general manager Mike Mayock a racial epithet), and posting a recorded conversation with Raiders coach Jon Gruden to YouTube.

In 10 NFL seasons (the first nine with the Pittsburgh Steelers), Brown has caught 841 passes for 11,263 yards and 75 touchdowns.

He is a seven-time Pro Bowl selection and four-time All-Pro.

Ramsey travels with Jags

Disgruntled cornerback Jalen Ramsey is back with the Jacksonville Jaguars and was on a plane to Denver for Sunday’s game against the Broncos, an ESPN source confirmed Saturday.

NFL Network was the first to report that Ramsey was on the team flight to Denver.

He is still listed as questionable for Sunday’s game.

Ramsey didn’t practice throughout the week, citing an illness and lower back and hamstring injuries, while taking personal time to be at home in Nashville, Tenn., for the birth of his second daughter.

On Uninterrupted’s “17 Weeks” podcast on Sirius XM, Ramsey reiterated his trade request on Thursday because he has lost respect for the franchise.

“I’m not sure if I’ve played my final game for the Jags yet or not, but my trade request still stands. For me, respect is a huge thing,” Ramsey, 24, said. “I kinda touched on it a little bit last week in last week’s podcast, but once respect is lost for both parties, I think it is time to part ways.”

Since joining the Jaguars as the fifth overall selection in the 2016 NFL Draft, Ramsey has not missed a regular-season game. The two-time Pro Bowler has 210 tackles and nine interceptions in 51 games over three-plus seasons.

Newton kepy injury quiet

In his first public comments since being sidelined, Carolina Panthers quarterback Cam Newton confirmed he has a Lisfranc injury that he says he kept secret from his own team.

In a YouTube video blog published Friday, the Panthers’ longtime starting quarterback revealed he has a mild Lisfranc sprain on his left foot, an injury he says he suffered in the team’s third preseason game against the New England Patriots last month.

Accompanied by a cigar and a glass of wine, the three-time Pro Bowler and 2015 NFL MVP admitted that he did not inform head coach Ron Rivera or the team that he was injured — even when he realized warming up before the season opener against the Los Angeles Rams that he was not himself.

“I was hiding an injury where I could have easily said, ‘You know what, Coach, I don’t think I’m ready. Maybe I need to kind of consider sitting this one out for the betterment [of the team],’” Newton said, adding that he told some on the coaching staff that he was fine even after they asked if was healthy.

Reasoning that he stayed silent partially because of his “Superman” persona, Newton said he “got in my own way. Because, automatically, I thought, ‘I’ve got to play Week 1. I can’t let my fans down. I’ve got to be there for my team.’”

Newton, already coming off an offseason shoulder surgery on his throwing arm, did not look like himself as the Panthers dropped their first two games against the Rams and Tampa Bay Buccaneers. Newton said he finally told Rivera after he couldn’t push off his foot to attempt a potential game-winning touchdown on 4th-and-1 at the Tampa 2-yard line in the waning seconds — with Carolina instead direct-snapping to Christian McCaffrey.

NFL Network reported Tuesday that backup Kyle Allen is likely to be the starter for several weeks. Allen threw four touchdown passes and led the Panthers to their first win of the 2019 season in Week 3 at Arizona.

In the season’s first two games, Newton has completed 56.2 percent of his passes for 572 yards. In 89 pass attempts, he has not thrown a touchdown pass and has one interception.

Newton has two years remaining on his five-year contract extension. The 30-year-old is owed more than $21 million, including a $2 million option bonus, for the 2020 season.
